Title: Improvements in shuttles for looms
IPC: D03J5/00
Filed: 1932-12-13
Abstract: 411,854. Loom shuttles. COHEN, A., 462, Keizersgracht, Amsterdam. Dec. 13, 1932, Nos. 35367 and 35368. Convention dates, Jan. 11 and April 12. [Class 142 (iii).] A shuttle, the cross-section of which conforms to that of the shed, contains a bobbin the body of yam on which is flattened or distorted to correspond with the shape of the shuttle. As shown in Fig. 3, the shuttle a of trapezoidal section is provided with a peg e of oval section which is pushed into the body of yarn to distort it. In some cases, the shuttle is oblong in section. As shown in Figs. 4 and 6, the peg is formed in three parts of which the central part 4 of wedge formation is pivoted on a fixed spindle 5 carrying cam surfaces 32, 33 adapted to engage the other parts 2, 3 of the peg. When the peg is lowered, it expands a round bobbin into flattened form so that it can be inserted into the upper side of the shuttle. In a modification, the outer parts of a threepart peg are connected by springs, a shorter central wedge part serving to expand the peg. In the form shown in Fig. 9, the bobbin is flattened when the peg is turned through a hole in the side of the shuttle, by forming the peg in two parts 25, 26 pivoted at 35, 36. The peg in either form may be detachable from the shuttle or pivoted on a carrier detachably mounted in the shuttle. A tubular cop may be distorted by being forced into a shuttle of elongated shape.

Abstract: 364,763. Show cards. CHILTON, J. E., Holly Lodge, Shiplake, Henley-on-Thames. Nov. 26, 1930, No. 35530. [Class 3 (ii).] A flexible sheet d carrving advertising matter is stretched between two end members a, b by means of a strut c, which is preferably resilient and is sprung into slots g in the end members, the edges of the sheet being brought round the curved edges of the end members and secured to their rear faces e so as to leave the front face of the sheet perfectly smooth. The end members may be of circular instead of recta ngular section. As shown, the strut c is cut longitudinally at h, leaving outer portions i which engage the lower slot g, and a central portion k which serves as a supporting strut. Alternatively a separate strut may be attached. A number of the devices may be assembled side by side, either with all the members a, b vertical, and connected by cardboard clips, or else with alternate cards having these members vertical and horizontal, in which case the horizontal member p of one card is connected to the vertical member n of the adjacent card in the manner shown in Fig. 4. This connection is effected by an elastic band s which is passed through a hole r in the member p and carries a ring t which engages an aperture u in the member n.

Abstract: 1,074,257. Making tubes. SCOTT PAPER CO. Aug. 31, 1964 [Sept. 4, 1963], No. 35635/64. Heading B5A. [Also in Division F2] Helically wound tubes of, e.g. paper are made by feeding a succession of sheets 2, having adhesive applied thereto, into a cylindrical cage formed by an array of rollers, each of which rollers, rotates about its own axis and is skewed relative to the longitudinal axis of the cage. The sheets are thrown centrifugally against the inside of the cage and are advanced therethrough by virtue of their contact with the rollers, the tube thus formed being withdrawn continuously from the cage. Moulding material 14, e.g. a foaming polyurethane mixture may be introduced through nozzle 15 into the rotating advancing tube and centrifugally moulded thereagainst. The paper tube may be retained upon the finished article, which is preferably subdivided by saw 16 into lengths, or may be stripped therefrom.

Title: Measuring radiation absorption or radiation emission
IPC: G01N23/08
Filed: 1975-09-02
Abstract: 1526556 Radiation scanning PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 2 Sept 1975 [5 Sept 1974] 36096/75 Heading H4F A processing and data storing system for evaluating the distribution of radiation absorption or emission over a plane by measuring line integrals of the function along sets of parallel lines in the plane at different orientations and calculating from these integrals the required distribution, comprises a processing stage shown in Figure 2 and a storage and output stage shown, for example, in Figure 3a. Measured signals representing the line integrals are fed into a shift register 110 and then via a gate 140 into a second shift register 120. A third register 130 contains weighting factors by which the integrals are to be multiplied and pairs of signals are fed cyclically, one from each of registers 120, 130, to a multiplier 180 where they are multiplied and the total of the products is formed at 170 for each set of measurements. The output signal is then stored in a storage tube circuit, in the case of Fig. 3a using two storage tubes 210, 220. A polarity selector 213 directs positive signals to the grid of tube 210 and negative signals, via an inverter 240, to the grid of tube 220. The two tubes are scanned synchronously and their outputs are subtracted by a differential amplifier 250 to give a final output 7 for visual display, e.g. a display cathode ray tube. Other cathode ray tube storage circuits can include a single storage tube with the cathode-anode voltage being switched between high and low values depending on the polarity of the input signal, Fig. 3b (not shown); having confronting camera and display tubes, the input signals being sent to one or the other again in dependence on their polarity, Fig. 3c (not shown); or using a display,tube to give an input to a light modulating tube having a dielectric mirror output screen which modulates the polarity of linearly polarized incident light, Fig 3d (not shown).

Abstract: 1510729 Stress meter UNITED STATES DEPARTMENT OF COMMERCE 3 Sept 1975 [3 Sept 1974] 36261/75 Heading G1G A vibrating wire stress meter comprises a highlytensioned wire 17 anchored at its ends into diametrically-opposed wall portions of a cylinder 15; an electromagnet 51, 53, 55 for both "plucking" the wire and detecting the resulting resonant vibrations (the frequency of which is dependent on forces acting on the cylinder 15); and a wedge- and-platen assembly 30, 31 for anchoring the cylinder in a borehole. The meter described is intended for measuring stress in rocks. Details are given of the method of assembling the meter by keeping wire 17 under tension while sleeves 19, 21 are extruded into recesses 23, 25 to anchor the wire ends. In use, the meter is inserted in a rock borehole by a special tool which then pulls on wedge 30, shearing a rivet 33 as it does so, to anchor the meter in position. The magnet coil 51 is energized via cable 3 with a manually-controlled frequency signal to induce wire vibrations. The coil is also coupled to a readout unit which measures the duration of the first hundred cycles of vibration following the plucking of the wire and thereby displays the vibration period numerically.

Abstract: 817,100. Metal-vapour lamps. GENERAL ELECTRIC CO. Ltd. Dec. 21, 1956 [Dec. 22, 1955], No. 36804/55. Class 39(1). A U-shaped discharge lamp 1 enclosed in an outer jacket 4, and having a filling comprising an alkali metal vapour, has the envelope wall on the outer part of each limb of the U deformed outwardly in a series of grooves. As shown, the grooves 23 may extend circumferentially. Alternatively they may be inclined to the axis of each limb 2, or may run parallel to the axis. In any case the grooves are confined to the outer part of each limb, so that the spacing between the limbs may be kept very small. They are preferably arranged symmetrically with respect to the plane containing the axes of the two limbs, and the depth and width of the grooves should be small compared with the diameter of the U-tube. The metal filling tends to collect in the grooves, which are cooler than the remainder of the envelope, and which, being uniformly distributed along the lamp, thus maintain a more uniform distribution of metal vapour. A typical application is a sodiumvapour lamp containing a neon-argon filling at about 10 mm. and having an inner coating of sodium-resistant glass. Some suitable dimensions are given. Each limb may have a closefitting insulating sleeve 13, as described in Specifications 801,482 and 816,043. and the bend of the U is supported by a spring clip as described in Specification 815,782. Starting wires 18 attached to the electrode lead wires 7 may be wound round each limb.
